Clearing the Air in Gas Delivery

MIG and TIG welding, plasma cutting, laser cutting or welding all require compressed gases. How these gases are stored, handled and used will determine the extent that the overall cost of these gas products impacts your bottom line. The correct gas delivery system will provide the most economical and efficient results to complement any of these applications – and the normal starting point for all of them is a cylinder of gas and a regulator.

Common Shielding Gases Used for Arc Welding

Each gas has different properties that affect how it responds under the heat of a welding arc, include its reactivity, ionization potential and thermal conductivity. Reactivity effects whether or not a certain gas or gas mix can be used with certain materials. These properties also affect various shielding gas operating characteristics and effect bead shape and penetration profiles.(Click on photo to enlarge it)
The variety of shielding gases used in arc welding can be confusing as to when to use which gas for which application. Here are some basic guidelines to follow.
